Nonsense. "Rustam Azhiyev" is a Chechen name. But of course, whatever the Muscovites say must be true. Right?
I notice the putinards wave the info around like a nukrual bedsheet the U.S gave the Russkies a heads up, and inferring they were in on it. Using the same retarded logic you could say the Russkies were in on the Boston bombing because the FSB reportedly gave the the U.S a heads up. See how it works.
